Why teams connect ClickHouse and Dun And Bradstreet

Flow Dun And Bradstreet data into ClickHouse in real time — no exports, no schedulers, no custom scripts.

Dun And Bradstreet is a read-only source: Stacksync reads its data in real time and delivers it into ClickHouse, so ClickHouse always reflects the current state of Dun And Bradstreet — without exports, scripts, or schedulers.

The CRM feeds the warehouse and the warehouse should feed the CRM: relationship data flows one way, and computed scores, segments, and customer context flow back. Most teams build the first half as a batch pipeline and never quite get to the second.

Stacksync does both with one connection. Identity Resolution (Match / cleanseMatch), Criteria Search, Monitoring Notifications, Company Information (Data Block) from Dun And Bradstreet land in ClickHouse as live tables, updated within seconds, and columns computed in ClickHouse write back to fields in Dun And Bradstreet. There is no separate ETL and reverse-ETL stack to stitch together and no jobs to babysit.

Common use cases

  • 01 Pull D&B risk and credit signals (PAYDEX, Failure Score, D&B Rating) into a warehouse for credit-risk, vendor-risk, and third-party-risk analytics.
  • 02 Sync the D&B corporate family tree (parent and subsidiary DUNS) into the CRM so ABM and territory owners see full account hierarchies and roll pipeline up to the global ultimate.
  • 03 Consolidate logs and business records from multiple sources into MergeTree tables for retention and reporting.
  • 04 Land product event data alongside synced CRM accounts so analysts join usage and revenue in one place.

Common sync patterns

A single customer view

Join Dun And Bradstreet's relationship data with billing, product, and support data in ClickHouse to build the customer picture the CRM alone cannot hold.

Cleanup that sticks

Deduplication and normalization done in ClickHouse can be written back, so warehouse-side cleanup actually fixes the CRM.

CRM analytics on live data

Accounts, contacts, and activity from Dun And Bradstreet are queryable in ClickHouse moments after they change, so dashboards stop lagging the reality they describe.
